Patented Nov. 16, 1915.

Original application filed May 28, 1908, Serial No. 436,310. Divided andthis application filed February 11, 1909, Serial No. 477,381. RenewedApril 2, 1915. Serial No. 18,838.

To all "whom it may concern:

Be it known that I, EDWARD H. GUYER, a citizen of the United States,residing at Rock Island, in the county of Rock Island and State ofIllinois, have invented certain new and useful Improvements inRegistering Mechanism, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to registering devices such as are employed incomputing machines of various kinds.

The object of the invention is to provide a dial mechanism forindicating the results of various arithmetical operations, such asaddition and subtraction, which is simple and substantial inconstruction and, at the same time, accurate in operation.

This application is a division of my prior application, filed May 28,1908, Ser. No.

436,310, for combined typewriting and com-.

puting machines. v

In the present application I show only such parts of the machine whichconstitute the subjectmatter of said prior application as are necessaryfor a clear understanding of the dial mechanism per .96.

In the complete machine there are various devices, with which thepresent application is not concerned, which cooperate with the dialmechanism, and for an understand ing of these matters reference may behad to the said earlier application.

In the accompanying drawings, Figure 1 is a front elevation of theregistering mechanism. Fig. 2 is a plan view of the same.

Fig. 3 is a transverse section through the dial supporting frame. Fig. 1is a vertical longitudinal section showing the quill bearings and clutchmechanism. Fig. 5 is a perspective view showing a portion of the quill,the stationary shaft, and the shuttle. Fig. 6' is a detail perspectiveof the shuttle. Fig. 7 is a detail perspective of the dial-releasingdog. Fig. 8 is a longitudinal section of the same. Fig. 9 is a face viewof one of the dial supporting disks. Figs. 10 and 11 are edge views ofthe same; the former showing a short and the latter a long hearingcollar. Fig. 12 is a face view of one of the dials. Fig. 13 is an edgeview of the same. Fig. 1 1 is a face View of one of the dials showing amodified construction for use with the form of supporting disks shown inFig. 11. Fig. 15 is an edge view of the same, and Fig. 16 is aperspective view of one of the carrying pawls.

The registering mechanism consists essentially of a series of dialsarranged and actuated in a manner which will presently be described.These dials are supported by a frame which comprises a base 11 andupstanding end plates 12 and 13. The upper face of the base 11 isconcaved to receive the lower part of the dials 11 and 15 and the dialsupporting and spacing disks 16 and 17. The concaved face of the base islongitudinally grooved or recessed at 11 to receive and rigidly supporttubes 18 and core rods 19.

Each of the tubes 18 is formed with a series of evenly spacedtransverse'slots. A series of dial supporting disks 16-17 have theiredges entering the tube slots and are accurately centered and rigidlysupported by thecore rods 19, which engages notches 16 17 formed in theedges of the disks. By supporting the disks in this manner one of thedisks with its dial can be'removed for repair or replacement withoutdisassembling the other dial. Each ofthe disks has a central, circular,aperture surrounded by a bearing collar 16 or 17 to support a dial.

The dials 14, like the supporting disks, are formed of sheet metal, eachdisk having a series of equally spaced notches in its periphery. Theteeth formed by these notches are bent laterally and the outturned faceof each displays a numeral, there being ten such teeth numbered 0 to 9,inclusive. Each of the dials is centrally apertured, the periphery ofthe aperture be ing notched to form a series of ten inwardly projectingteeth 14 in radial alinement with the numeraldisplaying faces abovereferred to. These teeth are designed to be engaged by dial-turningdevices later to be described.

14 is a bearing collar or hub adapted to fit the outer face of thecollar 16 of a supporting disk 16 and to rotate freely thereon.

20 is a spring carrying pawl which consists of a half ring of flatspring metal having a centrally arranged outwardly extending projection20*" and in line therewith a laterally extending tooth 20". has its endsrigidlysecured, as by riveting, to the lateral face of the dial in aposition such that the extension 20 is disposed centrally of the notchbetween the numeral faces 9 and 0. Just outside of the hearing hub isare a series of ten rectangular perforations 1 t in radial alinementwith the peripheral notches of the dial and in circumferential alinementwith the tooth 20 of the carrying pawl.

lVhen one of the dials is in working position on its supporting disk,the tooth 20 of the carrying pawl is in circumferential alinement withan arcuate slot 16 in the supporting disk. This slot is in radialalinement with what may be termed the reading position of the. dials,this position being intermediate the two notches l6 formed in theperiphery of the disk and serving a purpose to be referred to later.

As the dial rotates with respect to its supporting'disk in the directionfor addition the tooth 20 of the carrying pawl moves into. the slot 16as the numeral v9 moves from the reading position and numeral comes intoreading position, this lateral movement of the pawl being due to thespring action of its arms. 1n the case of subtraction, with the rotationin the opposite direction, the tooth 20 moves into the slot as thenumeral 0 moves out of and numeral 9 moves intothe reading position. Asthe tooth 20 moves into the slot it comes into engagement with one ofthe'apertures 1a? of the dial of the next higher denomination andcarries it forward or backward, as the case may be, one point. 'As thetooth of the carrying pawl nears the end of the slot 16 in the carryingoperation, the in wardly extended beveled projection of the tooth 20engages one of the two beveled faces 16 and the tooth is thus liftedfrom theslot. The distance between the beveled surfaces 16 correspondsto 36 degreesof angular movement of the dial so that a movement of onepoint for the dial of next higher denomination is thus insured.

It is customary in writing numbers to separate the numerals in groups ofthrees as a matter of convenience in reading either by the use of commasor by spacino. The registering mechanism shown in this application wasespecially designed as a part of the combined typewriting and computingmachine which constitutes the subject matter of my copending applicationreferred to above, and in that machine the numerals are written'ingroups of threes. Accordingly the construction of every third dial andits supporting disks is slightly varied, the supporting disks 17 beingprovided with a bearing collar 17 wider than that of the disks 16,'andthe dial being provided with a correspondingly wide bearing hub 15?, the

This pawl width vof the collar being such that a dial 15 and itssupporting disk 17 occupy the space of two sets'of dials 14: andsupporting disks 16. Diametrically opposite lugs are formed on the hub15 to support the carrying pawl 20 in position to engage the adjacentdial supporting disk.

Referring now to the dial turning devices, 21 is a quill extendingconcentrically through the apertures in the series of dials and dialsupporting disks and rotatably supported in suitable bearings at eachend. A longitudinal slot 21 extends throughout the greater part of thelength. of the quill, being designed to receive a projecting part of theshuttle.

' 22 is a rigidly supported shaft extending through the quill 21 andprovided with a rectangulargroove 22 extending throughout its length.This shaft and the surrounding quill are designed to guide and turn ashuttle indicated as an entirety by 23, and comprising a body part 24-.and a collar 25. The body part 24 has hooked ends 24? and a centralnotch 2t having a width equal to the width of the collar The lattercarries a laterally projecting lug 25 hen the quill, solid shaft, andshuttle are assembledas is shown in Fig. 5, the body part 24: of theshuttle lies in the groove 22 of:

the shaft, while the collar 25 surrounds the shaft and body part at withthe lug 25 extendingoutwardly through the slot 21'of the quill. Thearrangement is such that the collar is free to rotate with respect tothe stationary shaft, but can move longitudinally only with the bodypart 24 of the shuttle, because thecollar engages the notch 2 1 of saidbody part. The lug 25 of the shuttle extends through the slot of thequill far enough to engage the inwardly extending teeth 14 of the dials,and by suitable rotation of the quill a dial engaged by the lug 25*.maybe turned any desired number of points.

Thelongitudinal movement of the shuttle to'bring it into-engagement withthe different dials is effected by means of a steel band 26 attached ateither end to one of the books 24 of the shuttle and adapted to beconnected intermediate its ends to suitable actuating means, as thepaper carriage of a typewriting mechanism.

27 is a pulley supporting frame in the form of a bar whichextendsthrough the base '11 and at its ends is bent at right angles, asindicatedin the drawings, to form suitable bearing supports for thespindles 28 and 29, said spindles being supported preferably-onadjustable. pivot points.

- 30 is a sprocket wheel mounted on the spindle 28 and 31 is a groovedwheel similarly mounted onthe spindle 29.

32 and 33 are brackets rigidly secured to the end plates 13 and 12,respectively. The

free end of the bracket 33 also the rear-- which are adjustably securedin position by.

means of the bottom nuts 36 and upon which are rotatably mounted groovedpulleys 34, the latter being secured in place by means of the top nuts37.

The pulley frame 27 is so disposed that the peripheries of the sprocketwheel 30 and of the grooved pulley 31 are in line with the path of theshuttle along the groove of shaft 22. The steel band therefore lies inthis groove throughout its length and on emerging therefrom at eitherend passes over the sprocket wheel 30 and pulley 31. The band isperforated throughout its length at regular intervals, the pitch of theperforations being equal to the letter space of the typewriter. Theseperforations engage vthe pin-like teeth of the sprocket wheel. From thissprocket wheel, on one hand, and from the grooved pulleys 31. on theother, the band passes rearward over the grooved pulley 34 between whichit is free to be engaged by actuating means such as mentioned above.

The quill 21 carries at one end a sleeve 38. The sleeve is formed with aball race constituting part of the ball bearing 39 which supports theend of the quill. On the 0pposite end of the quill is mounted a sleeve40 which is formed with a ball race constituting part of a ball bearing41 which is mounted in one arm of the bracket 32 and supports theadjacent end of the quill. The sleeve 40 is slotted at =10 and 40" andthe quill is formed with a spline or lug 42 which engages the slot 40",whereby the quill and sleeve are held against relative rotation. v

The shaft22 is rigidly supported at its left end by the bracket 43 (seeFigs. 1 and 2) and at its other end carries a sleeve 44 by which it issupported concentric with the quill. Between the end plate 13 and thebracket are mounted gears for effecting the rotation. in eitherdirection of the quill 21. V v

15 and 46 are annular gears concentric with the quill and mounted toturn freely on ball bearings. the gear 45 being carried by the bracket32 while the gear 36 is car- I ried by the end plate 13. V y

4.7 and 48 are gears mounted rigidly on a spindle 49, the gear47 meshingwith the gear 4.6 while the gear 18 lies adjacent but out of engagementwith the gear 45. The gears 45 and &8 are arranged to be actuated by acommon driving gear. not shown.

50 is a clutch which consists of a hub part. an annular rim part. anddiametrically opposite arms which lie in the slots 110 and. 40 of thequill sleeve 40. The rim of the clutch 50 is formed on either side withteeth 50 and 50 which are designed to engage notches -16 and 15 formedin the sides of the gears 46 and 45.

51 is a spindle, the inner end of which is guided and supported by thesleeve 4%. The clutch 50 is secured on the spindle between a fixed and aremovable collar. Suitable devices may be provided to move the spindle51 endwise in either direction, so as to move the clutch 50 into any oneof three position, viz: engagement with the gear 415; engagement withthe gear L6; and an inter mediate position in which it is out ofengagement with both of said gears. Bearing. in mind that the gears and$8 are simultaneously actuated by the common driving gear (not shown),it is clear that the quill will be rotated in one of two directionsaccordingly as the clutch 50 is in engagement with one or the other ofthe gears 45 and el6. This rotation of the quill transmitted to thecollar part 25 of the shuttle effects the turning of the dials in themanner previously stated.

lVith the dials and carrying pawls constructed as described, it isnecessary to pro vide some means to prevent the live dial, that is. theone engaged by the shuttle, from carrying with it one or more of thedials of lower denomination. this action being possible in case the dialof next lower denomination happens to be in position with its carryingpawl in the slot 16 of the interposed supporting disk.

A rock shaft 52, formed with a rectangular groove throughout its length,is mounted directly above the dials with bearing supports in the endplates 12 and 13. 53 is a pawl or dog having at its free end engagingteeth 53 and at its other end formed with a boss or sleeve to slidinglyengage the rock shaft 52. The teeth 53 are flat on their right sides andbeveled on their left sides and normally lie in the notches 16 of thedial carrying disks 16. These notches 1.6 lie adjacent the ends of thearcuate slot 16 of each disk so as to laterally expose the extension 20of the adjacent carrying pawl 20. when the latter is in either of thetwo positions of rest which it may occupy while its 1 collar 57 which isthreaded upon the sleeve of the dog. The steel band 55 lies within therectangular groove of the shaft throughout the length thereof, passingat the right over a sprocket wheel 58 mounted on the upright spindle 28,thence trans versely of the machine to the grooved pulley 59 carried bythe spindle 29. In assembling the parts the desired tension of the steelband is obtained by adjustment of the threaded collar 57.

The dog 53 is normally pressed downward by spring 60, so as to bring itsengaging teeth 53 in line with the notches 16 of the pawl-carryin disks16. The spring 60 is mounted upon the fork 61, the latter beingrotatably secured upon the sleeve of the dog between the face of the dogarm and a detachable securing nut or collar 53. The fork is preventedfrom turning by reason of its en agement with the sleeve 62' on theoverthrow detents 63, which sleeve is slid-' ably mounted on a rod 64:above and parallel to the shaft 52.

The overthrow detents are designed to prevent the overthrow of the dialwhen it iscarried by the dial of next lower denomination. The detentsare in the form of segments, two in number, which are pivotally mountedon the sleeve 62. The rod 64,- on which this sleeve is suitably mounted,is carried by upright end plates or bars 65 which are suitably guided tohave a. slight up and down movement. The frame formed by these end barsand the rod 64: is adapted to be actuated, that is, raised and loweredin unison with the movement of the shuttle. The object of raising thedetents is to lift them at the time the shuttle and dog 53 are moved sothat they may be free to move from one set of dials to another, thedetents and their carrying sleeve 62 being moved along the rod 6% by thefork 61 which engages a suitable groove in the detent sleeve. The detentsegments themselves are slotted to permit the passage through them ofthe rock shaft 52, and at their lower endsare formed with three dialengaging teeth 63*. Viith the dial in a normal position of rest themiddle one of the teeth 63 projects between two of'the numeraldisplaying faces of the dial in position -to be engaged as'the dial isturned. Such engagement causes the oscillation of the segment, thuscausing oneor the other of the outer teeth 63 to pass into the nextadjacent notch in the dial. The movement of the dial is thus arrested,inasmuch as the oscillation of the segment is limited by engagement withthe rock shaft 52. I

The connection between the dog and the sleeve of the overthrow detent issuch that the detents are always maintained in position to engage thetwo dials of next higher denomination than t is live dial. Two of thedetentsegments are necessary on account of the dials with intermediatespacers, for a single segment would be inoperative when it fell in oneof these spaces. lVith two segments, the engagement of one tion isalways insured. Of course, the use of a second segment might be avoidedby making the width of the numeral displacing faces of the dials 16equal to the width of the bearing hubs 15 I have not in the presentapplication shown the mechanism'for bodily lifting the detents, as thatmechanism constitutes no part of the present invention. For a detaileddisclosure of this mechanism, reference may be had to my priorapplication hereinbefore referred to. j

It is clear that the sprocket wheel 58 will move the steel band 55 andwith it the dog 53 in unison with the paper carriage and the shuttle 23.The parts are assembled so that the dog 53 is always just one space tothe right of the dial engaging lug 25 of the shuttle 23. Consequently asthe shuttle moves into engagement with the dial next to be turned, thedog moves into position above the adjacent dial of next lowerdenomination and one or the other of its teeth 53 at the same timeengages the pawl ex tension 20 of the last mentioned dial in case it isin position to bring said extension in line with either of the notches16 of the dial supporting disk. By this engagement the dog withdraws thetooth 20 of the pawl from engagement with the live dial; that is to say,the dial next to be turned. Before the dog 53 can move another step tothe right, it must be lifted to disengage it from the pawl projection 20and to this end I provide means for rocking the shaft 52 so as to liftthe dog slightly at the time it is advanced, in unison with the shuttle.It is clear that the momentary lifting of the dog releases the carryingpawl which may have been engaged by one of the dog teeth and permits thedog to move in unison with the paper carriage one space to the right,engaging in such'movement the pawl extension of the dial over which itmoves in case such extension chances to be in the path of either of thedog teeth. I have not shown the means for effecting the rocking of shaft52 as said means constitutes no part of the present invention.

The operation of the recording mechanism will readily be understood fromthe descripion which has been given. The steel band 26, being connectedto some suitable actuating means such as previously described, theshuttle is moved successively into engagement with the internal'teeth ofthe dials and when the shuttle is thus brought into engagement with anyparticular dial, the latter may be turned through any number of pointsby suitable actuation of the quill e driving gears. When the clutch 50engages the gear 45, the quill is turned in one direction, viz., thatfor addition, and when the clutch engages the gear 46 the quill isturned of them with the'dial ofthe next denomina in the other direction,for subtraction.

described. Similarly, in the operation of subtraction the dial of nexthigher denomination than the live dial is moved back one point when thecharacter 0 of the live dial moves out of and the numeral 9 moves intothe reading position.

As the shuttle is moved from left to right, engaging'one after anotherof the dials, the dial releasing dog 53 is moved in unison with theshuttle, in the manner previously described, so as to prevent thetransmission of the movement of the live dial to any oi the dials oflower denomination.

WVhat I claim is 1. The combination of a plurality of spaced supportingdisks, having each a laterally extending bearing collar, a plurality ofregistering dials rotatably mounted on I the disks, and means carryingthe supporting disks adapted to permit the detachment of any diskindependently of the others.

In testimony whereof I affix my signature, in presence of two witnesses.
